Simple calculation of 43 * 68-43 * 48

43*68-43*48
=43*（68-48）
=43*20
=860

The height of a trapezoid is 4.8 meters. If the upper and lower bottoms are unchanged and the height is doubled, the area will be increased by 8.4 square meters, then the original trapezoid area is 4.8 meters______ Square meters

According to the stem analysis, if the top and bottom of the trapezoid remain unchanged and the height is doubled, the area will be doubled. Suppose the area of the original trapezoid is a, then the area of the increased trapezoid is 2a, 2a-a = 8.4 & nbsp; a = 8.4 A: the area of the original trapezoid is 8.4 square meters, so the answer is: 8.4

Solution equation: (1 + 50%) x * 80% = 60

(1+50%)x*80%=60
1.2x=60
x=60÷1.2
x=50

If a triangle and a parallelogram have the same base and height, and the sum of their areas is 45 square centimeters, then the area of the triangle is______ Square centimeter

45 (1 + 2), = 45 (3), = 15 (square centimeter); answer: the area of triangle is 15 square centimeter, so the answer is: 15

In the series of consecutive integers of minus 45, minus 44, minus 43,..., 20052006, what is the sum of the first 100 consecutive integers
Is the answer right? Does anyone know the answer?

100*(-45)+100*99/2=450

As shown in Figures 1, 2 and 3, points E and D are the points on the two adjacent sides of positive △ ABC, positive quadrilateral ABCM and positive Pentagon abcmn with point C as the vertex, and be = CD, DB intersects AE at point P. in Figure 1, the degree of ∠ APD is 60 ° in Figure 2, and the degree of ∠ APD is 90 ° in Figure 2___ ．

In △ Abe and △ BCD, ab = BC ∠ Abe = ∠ bcdbe = CD, ≌ Abe ≌ BCD, ≌ EBP = ∠ BAE, ∤ APD = ∠ BPE = 180 ° - EBP - ∠ BEP ∤ EBP = ∠ BAE, ∤ APD = 180 ° - BAE - ∠ BEP = Abe

Given the points a (1,0,1), B (4,4,6), C (2,2,3) and D (10,14,17), it is proved that a, B, C and D are in the same plane

Find the vectors AB, BC, CD, Da, and then use the mixed product
