7x8=56 (area of the rectangle of the “house” shape)
11-8=3
7x3=21x1/2 (how to find area of the triangle)
10.5
So the answer is 10.5 cm2 (centimeters squared)
Answer:
656×1000
Step-by-step explanation:
Answer:
gradient = 9
Step-by-step explanation:
The gradient of the tangent at x = a is the derivative
Differentiate using the power rule on each term
(a ) = na and ( constant ) = 0
y = 2x² + 5x - 3
= 2.2 + 5 - 0
= 4x + 5
( x = 1 ) = 4(1) + 5 = 4 + 5 = 9 ← gradient of tangent
Last choice I think good luck tho
